Add multiple python kernels like 3.6.x and 3.7.x to jupyterhub

my default python version is 3.6.8 which is installed from python sourcefile, and i am able to run jupyter notebook. Python path: /share/apps/platform/ai/py36/3_6_8/bin/python3

Now i am trying to add 3.7.6
Python path: /share/apps/platform/ai/py37/3_7_6/bin/python3

# jupyter-kernelspec list
Available kernels:
  python3    /share/apps/platform/ai/py36/3_6_9/share/jupyter/kernels/python3

Please guide me to add multiple python kernels.
